Anesthesia machines are specialized medical devices used to deliver anesthesia to patients during surgical procedures. They mix gases, such as oxygen and nitrous oxide, with anesthetic vapors to create a safe and controlled environment for patients. The machine also monitors vital signs, ensuring that the patient's heart rate, blood pressure, and oxygen levels remain stable throughout the procedure. These machines are equipped with various components, including a ventilator, which helps patients breathe if they are unable to do so on their own. Anesthesia machines are essential in operating rooms, allowing anesthesiologists to provide effective pain relief and sedation while closely monitoring patient safety.
